T0 all whom, t may concern:

Be it known that I, IsAAc G.WA'rnRMAN, a citizen of the United States,residing at Santa Barbara, in the county of Santa Barbara and State ofCalifornia, have invented new and useful Improvements in ElectricalMixing- Valves, of which the following is a specification.

This invention relates to electrlcalmixmgvalves.

The object of the present invention is the provision of an improvedelectrical valve mechanism especially adapted for use in con' iiuids bythe use of' one electrical pushbut.

ton and the electrical operation of another valve of novel constructionby another electrical push-button, successive manipulations ot' whichgradually open or gradually close the valve to thereby obtain adesiredmixture of the fluids or either of them separately.

The invention resides in the novel features and combinations of partsset forth indetail hereinafter and recited in the appended claims. lnthe accompanying drawings, Figure 1 is a section on line D D of Fig. 5;Fig. 2, asection on line B B oi' Fig. 1;. Fig. 3, a section on line A Aof Fig. 1; Fig. 4, asection on line E E of Figf; Fig. 5, a section online C C of Fig. l, and Fig. 6 a diagram showing the electricalconnections and push-buttons.

rl`he hot and cold water pipes 1 and 2 lead into the supply-valve casing3 through ports 4 and 5. The mixing-valve casing 6 has en,- try-ports 7and 8, connected with exit-ports 9 and 10 in the supply-valve casing 3by pipes 11 and 12 and is provided with an exit-pipe Specification ofLetters Patent.

ports 4 and 5 to ports 9 and 10 (sce Fig. 4) when the valve is open andto completely cut off the How of both hot and cold water when the valveis closed.

In the mixing-valve casing 6 is a tapered rotary valve 19, held in itsseat by a spring- `pressed ball 2O in a socket in a removablevscrew-threaded closure 21,en tered in the valvecasing. The mixing-valvehas a lune-shaped :..port or groove 22 in its side, which of suf lieientlength to connect either port 7 or 8 more or less with exit-pipe 13 orconnect both of said ports more or less with said exitpipe or altogetherclose communication between either port and the exit-pipe to entirelycut ofi1 the water. Accori'ling to the amount of rotation ot' this valveand the position it occupies, either hot or cold water will pass to pipe13 in desired volume, or any desired admixture of hot and cold water canbe obtained or the supply entirely cut otf though the valve 14 be open.

,The valve-casings 3 and 6 have formed therewith the curved arms 23(see' Fig. 3) and 24, Fig. 2, and the heads 2and 26 of the shell 27 ofthe respective solenoids 28 and 29 are fastened to these curved arms 23and 24 by screws 30. The solenoids are separately wound and separated byheads 31 and 32 and intermediate insulation 33, while' the respectiveterminals 34 of solenoid 28 and 35 of solenoid 29 are led out, as shownin Figs. 1, 2, and

Removable caps 36 and 37 cover the operative mechanisms at the upper andlower ends ot' the device.

fue heads 31 and 32 have sockets 38 and 39, intol which iit the ends ofguides 40 and 41, which abut the inner faces ot' caps 36 and 37.

The valves 14 and 19 have stems 42 and 43,

which pass through packings 44 and 45 and glands 46 and 47, which holdthe packings,

and said stems are centered in the respective guides 40 and 41. The stem42 has secured thereto a ratchet-wheel 48, whose teeth are arranged infour sets of three teeth cach, and

a square nut 49 is also secured on said stem. f
